After this I reinstalled the app, like this:

 sudo chown -R <current_user> /Applications/Sikuli-IDE.app
 sudo chmod -R ug+rw /Applications/Sikuli-IDE.app
 Drag Drop the app from the dmg to /Applications

Later in the day, I logged out, switched to another user and tried to run Sikuli and did not see the exception. Came back home and run it from the current account and did not see the exception again.

So, it seems that the problem is solved. However, when the exception was happening, it happened every time.

Based on the your "solution", I found out, that the file
Sikuli-IDE.app/Contents/Info.plist

is missing read right for the group and everyone levels in the installation file.

--- The following workaround has to be used after installing Sikuli.

To repair it, open a terminal session and enter the following command:

chmod og+r /Applications/Sikuli-IDE.app/Contents/Info.plist

This has to be done while logged in as the user, that was used to install Sikuli the first time.

After this, you can use Sikuli with every user on this machine from the standard Applications folders.
